Isolation, Amplification, and Sequencing of Human Mitochondrial DNA Obtained from Human Crab Louse, Pthirus Pubis (L.), Blood Meals

The ability to identify individual human hosts based on analyses of blood recovered from the digestive tract of hematophagous arthropods has been a long-term pursuit in both medical and forensic entomology. Blood meal individualization techniques can bring important advancements to studies of vector-borne disease epidemiology. Forensically, these analyses may aid in assailant identification in violent crime cases where blood-feeding insects or their excreta are recovered from victims or at crime scenes. Successful isolation, amplification, and sequencing of human mitochondrial DNA obtained from adult human crab lice fed on human volunteers are reported. Adult lice were removed from recruited volunteers frequenting inner city health clinics. Live lice were killed by freezing and subsequently air dried at ambient temperature. A saliva sample was obtained from each volunteer and served as a DNA reference sample. Volunteers were afforded free, approved pediculosis treatment. Individual lice were subsequently processed using procedures developed for the extraction of mitochondrial DNA from human hair, teeth, and bone. The resulting DNA was amplified by the polymerase chain reaction and sequenced. Our results point to valuable avenues for future entomological research.

Insecticides against headlice in Glasgow.

A postal questionnaire for describing current practices of insecticide usage for the prevention and treatment of pediculosis was sent to 53 pharmacists in Glasgow. 91% returned completed questionnaires. Between 19,000 to 36,000 bottles of insecticide against headlice were bought by the public in Glasgow in 1991. Most of these were sold in small volumes (less than 100 ml) and sales were highest during the autumn. Although pharmacists sold a range of different classes of insecticide, the most popular were those that contained malathion, the treatment for pediculosis recommended by the Health Board. Choice of treatment was probably influenced by advice given to the public by pharmacists and general practitioners. Clients preferred shampoo formulations. There was evidence that treatments were used prophylactically against headlice. However, there was little indication of large scale resistance to insecticides in the louse population. The results indicate that headlice remain a persistent problem in Glasgow, despite the public adhering to the advice of health professionals.

Pediculosis Prevention and Control Strategies of Community Health and School Nurses: A Descriptive Study

Pediculus humanus capitis (pediculosis capitis) affects several million school children in the United States every year and is more prevalent among children than all other childhood communicable diseases combined. Traditional treatment of pediculosis involves the direct application of pesticides to the scalp of infested individuals. Yet, a single-treatment, 100% ovicidal pediculicide has not been developed. Head lice can be easily detected by an educated screener. The National Pediculosis Association (NPA) recommends regular screenings to control lice outbreaks in school settings. Screening is utilized as a prevention strategy to facilitate early detection and minimize exposure to potentially toxic chemicals. Nurses working with children in the country's schools are in key positions to develop, initiate, and incorporate prevention and control strategies into their child healthcare agenda. An NPA national survey identified specific lice management strategies used by community health nurses (CHNs) and school nurses working in school systems. The purpose of this article is to report the prevention and control strategies used by the nurses. Results of this national survey indicated significant variation in management strategies. A national standardized approach toward prevention and control is not being utilized.

PEDICULUS CORPORIS Body lice and their nits, or eggs, are generally found in the seams of clothing, especially of underwear and heavy outer garments. Since the lice usually cling to the clothing even while feeding, they may be entirely absent from the body of an infested person. Their tiny bite marks can be found on the shoulders, between the shoulders, or about the waist. Eggs of the body louse are glued to hairs or fibers and take seven to
